It’s one of those “toss it together and forget it” recipes. Seriously, let the fridge do the work while you catch up on your summer reading (or wrangle the kids out of the sprinklers). Simple, colorful, and endlessly adaptable, this recipe is an easy side dish you’ll return to all season long.

Why You’ll Love These Marinated Cucumbers

First off, hello flavor! The tang from the vinegar, the slight sweetness of ripe tomatoes, the bite of raw onion, and the soft heat from red pepper flakes (if you’re feeling bold) come together in a symphony of summer freshness.

Plus, this recipe is incredibly flexible. Use apple cider or red wine vinegar. Swap in fresh dill or parsley. Like a little heat? Don’t skip the red pepper flakes. It’s a prime example of how marinated vegetables can be simple yet sensational.

Ingredients You’ll Need:

2 cucumbers (about 400 g), thinly sliced
1 pint (about 300 g) cherry or grape tomatoes, halved
1 small red or white onion (about 100 g), thinly sliced
60 ml (1/4 cup) apple cider vinegar or red wine vinegar
30 ml (2 tbsp) extra virgin olive oil
1 clove garlic, minced
1 tbsp (about 3 g) chopped fresh parsley or dill
Salt and pepper to taste
1/2 tsp (1 g) red pepper flakes (optional)

How to Make It:

Wash and thinly slice the cucumbers (about 0.5 cm thick).
Halve the cherry or grape tomatoes.
Peel and thinly slice the onion.
Whisk together the vinegar, olive oil, minced garlic, salt, pepper, and red pepper flakes in a bowl until well combined.
Combine the cucumbers, tomatoes, and onions in a large mixing bowl.
Pour the vinaigrette over the vegetables and gently toss to coat.
Cover and refrigerate for at least 30 minutes, preferably several hours or overnight.
Before serving, toss again and garnish with chopped parsley or dill.

Tips to Maximize Flavor (and Sanity)

Consider scooping out the seeds before slicing if your cucumbers are extra seedy.
Letting the mix marinate overnight deepens the flavor. If you’re short on time, even 30 minutes will do wonders.
Use a mandoline for uniform cucumber slices (just mind those fingertips!).
No fresh herbs? Dried dill works in a pinch—use about one teaspoon.
Want to bulk it up? Toss in some feta or chickpeas.

The Story Behind This Summer Salad

Growing up, this dish was always on our summer table, nestled between watermelon bowls and grilled chicken platters. My mom would prep it in the morning, and by dinner, the cucumbers were perfectly tangy and the tomatoes bursting with flavor. It was one of those “accidentally fancy” dishes that made guests feel special. Now, I make it whenever I need something light, bright, and nostalgic.

What to Serve with Marinated Cucumbers

This salad is a team player. Serve it alongside grilled burgers, chicken skewers, or even a slice of quiche for brunch. Thanks to its zippy acidity, it pairs beautifully with anything smoky or rich. Hosting a Mediterranean-style dinner? Add it to a spread with hummus, olives, and warm pita. Or just eat it straight from the bowl (we’ve all done it).

How to Store Leftovers

Store any leftovers in an airtight container in the fridge for up to 3 days. The vegetables will continue to soften the longer they sit, but the flavor only gets better. If it looks a little watery after day one, just give it a good stir. Avoid freezing—the cucumbers don’t like it one bit.

FAQs About Marinated Cucumbers, Onions, and Tomatoes

Can I use English cucumbers instead of regular ones?

Absolutely! English cucumbers are perfect since they have fewer seeds and thinner skins.

What if I don’t have fresh herbs?

No problem—dried parsley or dill works fine. Just reduce the amount (about 1 tsp).

Is this a make-ahead recipe?

Yes! In fact, it’s even better the next day.

Can I add other veggies?

Of course. Bell peppers, radishes, or even blanched green beans are tasty additions.
